I also got the game early (on Friday), & have been doing nothing but playing it every chance I get to. The combat is really engaging, making you think on your toes rather than holding your ground, & then attacking. Not to say that Dark/Demon Souls wasn't, but for most of the time I was heavy armor, shield & sword all the way through those games. From what I've played so far, there are little to no shields to use, so if you were the dodging type in ether game, you'll feel right at home. The new checkpoint system is great idea, kind of hybrid of both Nexis & Bonfires where you can walk around, level up stats/weapons, store items, buy stuff, & you can fast travel from the beginning.
I'd say my only nitpick so far are load times, but that's really it.
Quite a few actually, but when you have over 300 games, you're bound to re-buy things you've sold when you were younger. I've bought Burnout Revenge for the OG Xbox from a thrift store, then after playing it for about an hour I turned to eBay & bought a 360 copy. Metal Gear Solid about 2 times over (Essential Collection & Black label PS1) because my original was lost to time. Assassin's Creed 1 because I played it once on PS3, sold it, then bought it again when I got a 360 for points. If it counts (which I believe it does) all the N64, SNES, & NES games I use it own & then some. This would just go on forever if I keep typing, so I'll stop here.
I've pre-ordered a PS4 mainly for price, & games. I don't hate the XBO, im gonna get One (lol) down the line (I buy everything), but if you asked me which one I want more right now, it's PS4. When I mean, I pre-ordered it, I actually paid the whole thing off in full. Gamestop was asking for $100 just to pre-order, so I went to the bank on the way back, & thought hey I have the money now, & im gonna spend $400 in the long run, I just ended up buying the whole thing up front.
